DO-6309 series industrial dissolved oxygen analyzer

The DO-6309 series dissolved oxygen analyzer is an online intelligent dissolved oxygen detection instrument produced by our company through the introduction of foreign technology. It uses imported components and dissolved oxygen film heads, combined with good production processes and surface mounting technology, to ensure long-term stable and reliable operation of the instrument; Automatic judgment of electrode zero point and slope exceeding the limit; Optocoupler isolation protection for 4-20mA signal output, with no interference between input and output signals; EEPROM type memory, no need for backup batteries, data will not be lost after power failure; Small temperature drift, stable, and accurate; The unique design of the operation menu avoids tedious operations for users, making it incredibly convenient to use; Large screen multi parameter (simultaneous display of dissolved oxygen value, temperature, output current, etc.) LCD backlight display, intuitive and easy to read; The backlight will automatically turn off after three minutes without button operation, which not only saves electricity but also extends the service life of the meter; Adjustable screen contrast level; High and low alarm points can be set arbitrarily; The screen can directly display the alarm status and can be accompanied by ON/OFF signal output at the same time; The hysteresis setting function can be set arbitrarily to avoid frequent actions of the switch relay; RS485 communication is optional;. It can be widely used for continuous monitoring of dissolved oxygen values in solutions such as chemical fertilizers, metallurgy, environmental water treatment engineering, pharmaceuticals, biochemistry, food, aquaculture, and tap water.
